Hi,

I need some help understanding dmd and I'm wondering where I 
should ask.

I have made a multiple aliasthis implementation that currently 
only works for structs. If I try to use a class then the compiler 
segfaults in .
The implementation basically just changes aggregate.aliasthis to 
be aggregate.aliasthis(Type expectedType) and then that function 
picks a matching aliasthis option and returns it.

Thanks,
Rory

The segfault was because I forgot to mark one of my new methods as "final",
and it was messing with the poffset in baseOf.

I think this is relevant to anyone mixing D and C++, not sure if its for
everyone because I'm not sure where poffset comes from. Basically if a
struct works and a class causes the compiler to segfault in baseOf when
compiling your module, its probably this.
